AUTOMATIC COMPRESSION STOP AND WASTE COCK OR'VALVE.

To all whom it may concern .7

Be'it known that I, FRANKLIN G. HIRsT, a citizen of the United States, residing-in the city and county of Philadelphia, State of Pennsylvania, have invented a newand useful Automatic Compression Stop and Waste Cock or Valve, of which the following is a specification.

Iy invention relates to a compression and waste cook or valve, in which provision is made for closing and opening the meansfor the escape of the waste waterremaining in the cock and its connecting pipe or conduit, and consists of a supplemental valveto control the exhaust passage and adapted to seat Within the casing and on the seat aroundthe exhaust passage upon a flange, which seat and flange are inthe same plane'to form a continuous bearing surface for the supplemental valve. 7

It further consists of other novel features of construction, all as will be'hereinafter fully set forth. e

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable re sults, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that'my invention is not limited to the precise arrangement and organization of these instrumentalities as herein sh'own'and described.

Figures 1,"2"an'd 3 are vertical sectional views of a compression and waste cock embodying my invention, certain members thereofbeing in different positions in the different figures, Fig. 4 is a top ,or plan view of'a casingor shell of the cock. Fig; 5 is a vertical sectional'viewthereoff Fig. 6 is a bottom plan view of a-thimble employed, serving as the supplementalvalve; Fig. 7 is a side elevation thereof. Fig. Sis a sectional view on the line 7. Fig. 9 is a sectional View through the valve proper and a portion of the stem.

Similar numerals of reference indicate corresponding parts 1 in the figures.

Referring to the drawings, 1 designates a casing or shell of the cook or valve having the inlet opening 2 and outlet 3 with the Specification of Letters Patent.

partition 4 having a port or passage 5 therein, around which is the valve seat 6.

Tdesignates a valve which'is adapted to control the port 5 and which is insuitable stem 8, in order that independent rotary movement between these parts is permitted. As here shown, I have provided a neck 9 upon the valve 7, which is engaged by a suitably shaped rib 10 on the stem 8, whereby it will be understood that the said-valve will be raised and lowered with the stem, but that when the valve 7 is in engagement with the seat 6,.the stem 8 maybe independently rotated without imparting rotary movement to the valve, whereby injury to the valve will be prevented. e s,

Projecting at a suitable pointwithin the casing 1 above the valve seat 6 is. an imperforate flange 11 and at suitable points within the casing 1 are the bosses 12, the upperface of each of 'whichis situated in the same plane with the upper face of the flange 11 to form an even and continuous bearing surface therewith around the in terior'of the "casing'and each'of said bosses isflprovided with a passage '13, the inner ends of which communicate with the interi'or of the casing above-the flange and the outer ends of which open exterior of the casing 1, it being understood that'the upper face of such boss serves as a seat around the passage therein. I l4- designates'recesses in the fiange 11 on opposite sides ofth'e bosses '12 and extending a suitable distance upon each side of the opening to the passage therein, as will beunderstood from Fig. 4. l5 designates a supplemental valve here shown as a thimble which isfadapted for threaded engagement ,withflthe stem 8, and which ismovable in the opening formed by the inneredge of the flange '11. The valve 15 is providedwith ribs 16movable in the recesses'l' l in said flange 11, whereby it will be understood that the thimble is adapted for vertical movement but is prevented from 17 designates a shoulder on 'the' thimble 15, serving as the seat face, thereof and adapted toseat upon the flange 11 and the upper ends of the bosses 12, in order to control the passages-13 therein and by reason adapted to abut the bonnet When the valve is entirely opened, whereby the supplemental valve is firmly pressed against the flange andpassage seat, and a resilient device bearing on said supplemental valve to normally press and hold the same upon said flange.

2. In a device of the character stated, a casing, a valve proper for controlling the passage through the casing, a seat for said valve, a stem suitably carry'ng said valve, a flange in said casing above said valve seat, a boss in said casing having a passage therethrough to the exterior of the casing, the upper face of said boss forming a seat around said passage situated in the same plane With the upper face of the flange to form a continuous bearing surface therewith, recesses in saidiflange on opposite sides of said boss, a supplemental valve in threaded engagement with the stem and having a shoulder adapted to seat upon said flange and passage-seat, to control said passage, ribs on said supplemental valve movable in said recesses and With their ends spaced from the shoulder thereof, a packing for said shoulder With a portion thereof seated in the space between the ends of the rib and the shoulder to insuremovement thereof With said supplemental valve, and a resilient device bearing on said supplemental valve to normally press and hold the same upon said flange. v

3. In a device of the character stated, a

casing, a valve passage through the casing, a seat for said valve, a stem suitably mounted, a connection between said valve and the stem for permitting an independent rotary movement therebetween, an 'imperforate' flange Within said casing above said valve seat, a boss in said casing having to the exterior of the casing, the upper face of said boss forming a seat around said passage situated in the same plane With the upper face of the flange to form a continuous bearing surface therewith, recesses in said flange on opposite sides of said boss, a supplemental valve in threaded engages ment With the stem and having a shoulder adapted to seat upon said flange and pasproper for controlling the a passage therethrough sage-seat, to control said passage, ribs on said supplemental valve movable in said recesses and With their ends spaced from the shoulder thereof, a packing for said shoulder engaged by said ribs to insure movement thereof With said supplemental,

valve to remove the packing from the seat around the passage, and a resilient device bearing on said supplemental valve to normally press and hold the same upon the flange.
